Possible types m for FIR filters created for a list {a1,a2,…,ak} of amplitudes are:

The default type is .

The frequency sampling method uniformly samples the frequency domain from 0 to .

FrequencySamplingFilterKernel by default uses a sampling of the frequency domain at integer multiples of , where is the length of the filter. With "Shifted"->True, the frequencies are shifted from 0 by .»
